† _{In addition to the events shown in this table, each of the 64 channels can also be synchronized with the transfer completion or alternate transfer}
completion events. For more detailed information on EDMA event-transfer chaining, see the TMS320C6000 DSP Enhanced Direct Memory
Access (EDMA) Controller Reference Guide (literature number SPRU234).
‡ _{The PCI and UTOPIA peripherals are not supported on the C6414 device; therefore, these EDMA synchronization events are reserved.}
§ _{The VCP/TCP EDMA synchronization events are supported on the C6416 only. For the C6414 and C6415 devices, these events are reserved.}
